Toroidal core

toroidal core without cut is toroidal and wounded in the same direction of closed flux path,  its magnetic performance is the best of all with less magnetic leakage.
It's is easy and high efficient to be wound by using toroidal winding machine. 
Current  transformers, Voltage transformers.  
Using high quality CRGO silicon steels with low iron-loss & high permeability in thickness of 0.05mm, 0.08mm, 0.1mm, 0.2mm, 0.23mm, 0.27mm, 0.3mm, 0.35mm. 

Ring-Core Dimention.

Performance: We can choose the relevant material to satify customers’ demands of different quality.  
Cores with other specifications can be provided concerning to customer demand.
